Abstract (en)
[origin: EP3562266A1] A control circuit (30) for an induction heating device comprises a D.C. power supply (46), referenced to a ground connection (54) and configured to supply power to the induction heating device. A switching device (86) is configured to be selectively activated to control the induction heating device. The switching device (86) is connected on one end to the ground connection (54). A resonant load (36) is disposed between the D.C. power supply (46) and the switching device (86), the resonant load (36) comprises a capacitor (42) and an inductor (40) connected in a parallel configuration. At least one rectifying device (34) is disposed in series with the resonant load (36) and the switching device (86). The switching device (86) is configured to control current from the D.C. power supply (46) through the resonant load (36).
